WINDS??? CLEANER.

Application filed Jilly 2, 1921.

T 0. all whom it may concern Be it known that 1,.V1oron VIOLA, a subjectof the Kin of Italy, and a resident of the borough of anhattan, in thecounty of New York and State of New York, have invented certain new anduseful Improvements in Window Cleaners, 5f which the following isaspecification'.

This invention relates to improvements in window cleaners.

An object of this invention is to provide a device which simultaneouslycleans both sides of a window.

Another object of this invention is to provide such a device withcleaning elements adapted to work into the corners of a windew and whichmay be readily adjusted to occup convenient positions.

A urther object of this invention is to provide in such a device novelmeans for keeping the cleaning elements always in contact wlth thewindow when the device is in use.

These and other objects including ease in operation, efiiciency andeffectiveness are attained by the novel construction and arrangement ofparts hereinafter described and shown in the accompanying drawing,forming an essential part golf the disclosure, and in which 2-- Figure 1illustrates the application of the invention to a window.

Figure 2 is a side elevation of the device.

Fi re 3 is a front elevation of same (arms partly broken away).

Figure 4: is' a front view of the top portion thereof showing thecleaning elements turned through an angle.

In general the device comprises two flexible arms mountedat one of theirextremities on a block. These arms are provided at their otherextremities with removable and adjustable cleaning elements, the latterbeing adapted to contact with both sides of a window pane when applied,by means of the flexure of the arms and a tension bolt. Means fullydescribed below, are provided to regulate the lateral pressure of thecleaning elements and facilitate the latter remaining in contact withthe window during operation.

Referrin to the drawings in detail nu block substantially but havingslightly ta lar in sha e rec ngu p mounted the tapered ends upon whichare Serial lilo. aeeooe.

flexible arms 12. These arms made preferably from suitable wood andshaped to give the desired flexibility are secured at one of their endsin the tapered ends of block 11 by means of the bolts 13 and when thussecured slightly converge. By separately at taching the arms to theblock the device is prevented from splitting when the former are spreadoutwardly as would be the case if the arms and block were formed of onepiece. Block 11 is made of sufiicientlength so as'to permit the armsbeing passed over the frame of the window and any protru sions on thelatter.

Disposed at the upper ends of arms 12 are the cleaning elements 14.These cleaning elements are comprised of preferably square orrectangular shaped cleats 15 having soft pads 18 made of felt or othersuitable substance adhesivelyattached to their outer surfaces thecontours of which are similar to the cleats but of larger area so thatthey extend beyond the edges of the cleats.

Cleats 15 are provided with arcuated slots 17 adapted to engage thebolts 18, the slots being countersunk so that the heads of the boltswill not protrude from the surface ofthe cleats and cause the pads tobulge.

Disposed between cleaning elements 14 and arms 12' are the washers. 19and helical springs 20 the function of which will be explained below.

Bolts 18 are made of suiiicient length to extend through washers 19,springs 20 and the perforations inarms 12 and to engage wing nuts 21. I

Disposed over block 11 and parallel thereto is a tension bolt. 22 whichpasses through perforations in arms 12, the threaded end of whichengages a wing nut 23' adapted to regulate the tension on the arms. Theurpose of this bolt is to keep the arms rom spreading which might becaused by a change in the condition of the arms such as warping, etc.

Two sets of the elements 14 are provided, one for simultaneously washingboth'sides of the window "and the other for simultaneously drying same.These elements may be interchanged very easily.

To use the device the pads of cleaning elements 14 are moistened andsecured to arms 12. Arms 12 are then adjusted by means of tension bolt22 until the pads 16 touch each other at their outer surfaces. Bymanually spreading arms 12 apart sufiicient space sprin s 20.

may be obtained between the cleaning elements to clear the frame of thewindow.

The pressure of pads 16 of the cleaning elements 14: on bothsurfaces ofthe window is regulated by the manipulation of wing nuts 21', and theco-operative action of Thus the pressure of the cleaning e ements u onthe window may, within certain limitations, be regulated independentlyof the arms so that in case the latter for some reason fails ,-to causesufiicient pressure to be maintained the necessary additional pressuremay be produced in the manner stated above.

:lhe cleaning elements are constructed in such a manner that they fitinto the corners of the window. Being provided with slots 17 they may beturned at any convenient angle soas to fit into the corners of diamondshaped windows and the like.

After the window has been washed the wet cleaning elements are removedand dry ones substituted therefor to complete the cleaning operation.

From the'foregoing it is manifest that an efficient anduseful device forsimultaneously cleaning both sides of a window has been produced. Thedevice being operated from theinside eliminates the hazards usually en"countered by one when cleaning windows.

While certain referred embodiments of this device have em shown anddescribed,

I it will be understood that changes in the and surface pad, andresilient means for regulating the pressure of said elements upon anintervening object.
